Abstract
A device for automatic winding of a barrel spring of a watch includes an oscillating mass, an entry disk kinematically linked to the oscillating mass, two reduction disks and a ratchet driving disk, each reduction disk including a reduction wheel bearing at least four planetary wheels, and a transmission pinion about which the reduction wheel is loosely mounted, the entry disk being kinematically linked to the two reduction wheels such that, regardless of the direction of rotation in which it is driven by the oscillating mass, it rotates the two reduction wheels in mutually different directions, the planetary wheels forming, in each of the reduction disks, ratchets to connect in rotation the transmission pinion and the reduction wheel only when the reduction wheel pivots in a predefined direction of rotation, the predefined direction of rotation being identical for either of the reduction wheels.
